TLS "certificate could not be validated" clarification in report

**Describe the bug**
I believe the [device](https://multitech.com/product/conduit-model-mtcdt-l4e1-europe-uk/) to which the below report pertains does not support/offer TLS 1.3.


The text "certificate could not be validated" implies that there was a certificate, but it could not be validated _for some reason_ (issue with the cert/issue with the cert chain/issue with Testrun itself/etc.), as opposed to the fact that TLS 1.3 is not supported and/or a certificate was not presented as a result.

**Expected behavior**
If a service doesn't support/offer TLS 1.3, this should be stated as such, to remove any ambiguity over whether a certificate was presented.
